How It Works? Supply Chain
So, how does milk travel from the farmer to your refrigerator?
Bilkul Bazaar | Sunday Special
Every morning, millions of Indians open a milk pouch, pour milk into a glass or saucepan, and rarely think about the journey it has already made.
That milk may have started its journey several hours earlier at a dairy farm, passed through a collection centre and a chilling facility, travelled to a processing plant, been tested and pasteurised, packed, transported and finally delivered to the shop or doorstep.
So, how does milk travel from the farmer to your refrigerator?
1. It starts with the farmer
The journey begins at a dairy farm.
Farmers milk cows or buffaloes, often twice a day. The milk from many farmers in the surrounding area is brought together through a milk collection network.
For the farmer, milk is not simply a food product. It is a source of regular income.
2. Milk goes to a collection centre
Fresh milk is taken to a nearby collection centre, where it is weighed and tested.
Tests can check factors such as fat content, quality and whether the milk meets required standards.
The milk from many farmers is then combined.
This is the first important link in the supply chain: many small producers become one larger, organised supply.
3. The milk is chilled quickly
Fresh milk cannot simply sit around for hours.
It is therefore cooled rapidly at a chilling centre. Keeping the milk cold slows the growth of microorganisms and helps preserve its quality while it moves to the next stage.
This is why the cold chain is so important to the dairy business.
4. It reaches the dairy processing plant
From the chilling centre, tankers transport the milk to a dairy processing plant.
Here the milk undergoes several processes.
It is tested again, filtered and processed. Depending on the product, its fat and other components may be adjusted to achieve the required standard.
The milk is then pasteurised—heated to a controlled temperature for a specified period and then rapidly cooled.
The purpose is to reduce harmful microorganisms while maintaining the milk’s quality.
5. Milk is packed
Once processed, the milk is packed into pouches, bottles or other containers.
The package carries important information such as the type of milk, quantity, date and other required details.
Packaging does more than hold the milk. It protects the product and makes transportation, storage and selling possible.
6. Now the distribution network takes over
The packaged milk has to reach thousands of locations quickly.
Dairy companies use distribution networks involving transporters, distributors, milk booths, retailers, supermarkets and sometimes direct-to-home delivery.
Unlike many other products, milk has a relatively short shelf life.
That means the dairy supply chain has to work every single day, with very little room for delay.
7. The retailer sells it
The milk finally reaches the neighbourhood shop, supermarket, milk booth—or a delivery agent who brings it directly to your home.
The retailer earns a margin for selling the product.
By this point, a product that began as raw milk at a farm has passed through several businesses and logistical stages.
8. And finally, your refrigerator
You buy the packet and take it home.
The journey is complete.
Farmer → Collection Centre → Chilling Centre → Dairy Plant → Packaging → Distribution → Retailer → Consumer
WHO MAKES MONEY?
The price you pay for milk does not go entirely to the farmer.
The economics of the supply chain involve several costs and participants:
- The farmer earns from supplying milk.
- The collection network handles aggregation and testing.
- The dairy processor incurs costs for processing, quality control, packaging and operations.
- Transporters and distributors move the product through the supply chain.
- The retailer earns a selling margin.
- The dairy company must also cover administration, refrigeration, energy, manpower and other operating expenses.
The exact share varies considerably depending on the dairy, product, location and distribution model.
WHY IS MILK SUCH A DIFFICULT PRODUCT TO DISTRIBUTE?
Because time and temperature matter.
A packet of biscuits can remain on a shop shelf for months.
Milk cannot.
From the moment it leaves the animal, the clock is running.
That is why dairies need:
Collection + Testing + Chilling + Processing + Cold Storage + Transportation + Distribution
to work together almost seamlessly.
THE BUSINESS BEHIND YOUR MILK
The next time you buy a ₹20 or ₹30 packet of milk, remember that you are not simply buying milk.
You are buying the result of a daily supply chain involving farmers, collection centres, dairy plants, laboratories, packaging operations, transporters, distributors and retailers.
And all of them have to work together before that packet reaches your kitchen.
